As shown, particularly in Figure 1'7i, the posts 30 are formed in two:sectio ns, the upper section 44 beingfitted to abase member. 45 which rests upon the channeled base '25 and is, as previously mentioned, adapted to both rotate within and slide over the upper surtaceof the base 25'. r

A flange4'l secured 'to the base member-45gives stability to the postas wellaas torm-ing a meansto grip: the base 25. as occasion may require, as will with spaced liners 45 which ber 25 and. are in ce-operative'relation to. the 1 placed'on the base 25 and each post is adapted to be rotated through 180: degrees and'to. be longi- The base members 45 of theposts30' are formed with a reduced section 49 which is snugly. fitted between'the opposing faces of the liners, 45,, thus adding to the-lateral stability of the postsx30.

- Immediately bielowthe: above referred-to reduced section, the base member 45 is-again reduced .in section, and is fitted: withv a collar 52 which is securely fitted thereto and isadapted to fit between the. opposing faces 53 and154 of the stepped configuration of the liners 45.

Being at a point immediately adjacent to, the

lower faceot the collar 5.2, the remaining portion of the base member 45. is threaded to receive a.

1 1ut..54 having'a, flange 5'5 v v a The nut 54 isadapted' to rotate upon its threaded support, through a predetermined arc, the limits of which are determined by the following circumstances: (1) Contact between the nut 54 and. its flange 55, and the collar 52, (2),the engagement of pin57, see Figures 10 and 11, secured in collar 52 with pin 59 secured in the flange 55 of nut 54.

The purpose of this partial rotation will be hereinafter described. 1 i

The exterior of the nut 54 is provided with a few heavy threads upon which a second nut 62 is adapted to rotate.

The nut 62 is provided with a gear 63 which is formed integral therewith and which is adapted to engage one of the racks 32 or 33. As shown in Figure 17, the .gear 63 is engaging rack 33 and is rotated thereby when the rack is advanced or retracted.

There are two'posts 30, one adapted to be operated by rack 32, while, as-above stated, the other is operated'by rack 33.

End post construction:

A vertically movable rack 65 is adapted to move upwardly and downwardly within the'posts 30.

The lower end of the rack 65 rests against the inner and upper face 66 of the nut 62, a ball bearing 67 interposed between the end of the rack 65 and nut 62,.tends to reduce friction to a minimum. A spring 68 is placed in the upper ex:- tremity of the longitudinal passage 65' within which the rack 65 operates.

the rack while the opposite end of the spring abuts a plug- 70 which is screwed into the upper end of the passageway 65. The spring 68 forces the rack downwardly against the face 66 of the nut 62 at all times when the racks 32 and 33 and gears 63 are not actuated. As shown in Figures 8 and 17 the rack 65 is adapted to oscillate a stem '70 by means of a gear '71 which is fitted onto the end of the stem 70 which is journalled in a bearing 73 which is held in position by means of a bushing '74 screwed into the post 30. v

The stem 70 is formed with across member '76 upon each of which a pair of fingers 77 are ad- -justab1y fitted. as is clearly shown in Figure 17.

Figure 16 shows the inner face of one of the fingers and clearly shows a shallow '78 which is dimensioned to equal one half of the diameter of the stem 70' so that the fingers 7'7 may be brought together to any degree in order to accommodate various sized wires or coils. The fingers are held in position by means of set screws 80.

Having thus described the construction of the channeled'base and of the end posts, I will now describe the construction of the cross members and'the posts used inconnection therewith.

As shown in Figures 3 and 6, the exterior of the base member 25 is formed with longitudinally extending V shaped slots which are designed to accommodate guides 86 which are secured to the under surface of the cross arms 26 to keep the arms alignedthrough their travel distance.

As shown in Figures 2, 6, '7, 18 and 19 the cross arms 26 are also formed of channeled metal and, as previously stated, are held in slidable relation to the base member 25 by means of the guides 86 operating in the V slots 85.

The cross arms 26 are routed to accommodate racks 90 and 91. 'Each rackbeing opposite the other and in the same transverse plane.

The racks 90 and 91 are driven back and forth substantially as are the racks 32 and 33, however,

stepped faces of the liners 45.

the power necessary to move the racks 90 and 91 is derived from the motion of racks 32 and 33, by means of gears 94 and 95, each of which are driven by but one of the racks 32 and 33.

That is, gear 94 is driven by rack 32. The gear 94 is secured upon a stem 97 whichis provided with a circular flange 98, spaced above the gear 94 and which is adapted to rest against the An extension 99 of the stem 97 rests upon the bottom web 40 of the base member 25, thereby keeping the gear in constant mesh with its rack.

That portion of the stem 97 which enters the cross arm 26 is of reduced section and is fitted within a sleeve 100, upon which a gear.102 is fitted and which is in mesh with racks 90 and 91.

As shown in Figure 15, the sleeve 100 is provided with a slot 104 through which a pin 105 extends to engage one end face of a cam 107 which is formed on the upper face of gear 102. i

A bushing 109 keeps the sleeve 100 centrally aligned in a block 110 which rests between-the opposing sides of the channeled cross arms Y26 and which also rests upon liners 111 which are fitted to the inner faces of the crossarm.

gear 102 is continuous with the. section ofthe stem 97 which c'arriesgear 94, nevertheless, the

upper, or, reduced section 9'? of the stem 97 is v physically separated therefrom. The spring 68 bears against the upper end of The lower end of stem section 97' is squared and is fitted into a square recess 113 in stem 97 so that when gear 94 and stem 9'7 rotate stem section 97 also rotates and carrying pm 105 with gagement with racks 90 and 91 for the reason that pin 115 is carried with stem section 97 and bears against the lower face of gear 92 when it is lifted upwardly, thereby lifting the gear 102 from engagement with racks 90 and 91.

The posts 27 are adjustably fitted in the cross arms and are adapted to move in response to movement of racks 90 and 91.

The posts 27 are rotatably mounted in frames and 121. As shown in Figures 18 and 19, the

frames are identical in construction, that is, each i have parallel top and bottom pieces 122 and 123 which are joined together by end blocks 125 and The'end of post 27a is fitted with a half gear Cal that is adapted to engage and to be meshed with rack 90.

Post 275 is journalled in frame 121 and has its end fitted with a full gear 133 which is in mesh with a second full gear 134.

A half gear is formed in the same stock from which gear 134 is cut, and is adapted toengage and to be meshed with rack 91.

The lower ends of posts 2711 and 275 are journalled in bottom pieces 124, while full gear 134 and half gear 135 are journalled in bottom piece Having thus described the physical construction of the invention herein disclosed, I will now set forth the interdependence of the several features herein included and its operation in general.
